This cavity series of grinder pumps is designed for grinding and pumping sanitary sewage from submersible lift stations. The 810 and 815 series are intended to grind and pump reasonable quantities of items normally found in sanitary sewage applications. They can be installed in new applications or as a direct replacement for any grinder application of like size and capacity.  These series also can be installed in a Prepackaged Job Ready System or may be used in a Field Assembled basin package.  These pumps can be retrofitted to existing positive displacement pump installations.
